To all whom it may concern:

lle it .known that l, TiioMAs EDWIN CANN, a subject of the King of GreatBritain, residingr'at Leicester, in the county of Leicester, Fngland7have invented certain new and .useful in'iprovements Relating to the Re*'from a variety of causes, such as the rotting' of the canvas fabric dueto Wet getting into contact therewith when the Wheels are being washedas well as during inclement Weather or bad state of the roads. rThisperishing invariably renders the tire or cover unsrepairable by themanufactureraccording to the methods of. repair at present in vogue,While it often happens that a tire in 'this condition -is comparativelygood and capable of considerable wear on the tread surface.

The present invention has for its object to repair or reinforce tireswhich are dama-ged in the direction indicated, so as to impart to them anew lease of' life and tit 'them for considerable further wear.

The method of reinforcingl jackets ory outer covers according to thisinvention consists in applying thereto a durable nonf stretchablematerial, passing around'and iii;- ting snugly over and to the rib orbead and sewing it tightly thereover. A convenient material for thcpurpose consists of chrome tanned cowhide combined with which canvas isemployed the said'materials being molded to the shape and section o thetire cover so as to it closely theret` The rein forcement is sewn to thecover with a Wan thread or waterproof cord and ii desirable' the line ofstitches may be covered with a Waterproof coating. rihe invention willbe more fully l scribed with reference to the accompanying drawing,wherein TFigure l is a perspective View showing a transverse section ofa jacket or outer cover which is repaired or reinforced in accordancewith this invention. Fig. 2 is a side view of the completeoutcr coverfurnished with -a reinforcing` device according to this invention. 'FigQ is drawn to a smaller scale than Fig. l.

Referring to the drewing o is the ordi-v nary tire o1- cover and l) arethe ribs or beads which lit into the groove of the Wheel yrim to holdthe tire en the latter.

The perishmg of a tire usually takes place 6G y rotting or otherwisethrough the Walls of the tire at c near the ribs or beads the lat.- terfreqiiently breaking away as a result and thus rendering the tire orcover useless.

According to the present invention this por- 55 tion of a tire or coveris repaired or reinforced in a manner which consists of an internal andexternal application of durable non-stretchable material. The preferredmethod is to employ a combination of 7;

chrome tanned coivhide and canvas as will now be described withreference to F l. To the inside of the tire or cover a is :ip- 1plied apiece of leather l molded or shapedy to iii', closely to said cover. Apiece of can- 75 vas (represented in section by a dotted line) alsopreferably molded to fitithe .arch of the cover is then applied andextends from the point 3 around the rib or bead on one side of thecover` over the leather 1, 9,@

l round the interior arch and lovver edge. to apcint a on the oppositeside oi the cover. Ar piece of leather 5 molded. at 6 to tit closely upto the rib or bead lo is applied to 'outside of the tire and over the`end 3 of the 85?' canvas 2; The parts described are then secured bymeans of warf; thread or Waterproof cord s cwn'right through the tire orcover a at the points indicated at 7.' -Tlie lines of stitches 8 may becovered with a Waterproof so coa-ting such-.as india-rubber or cement tolill the stitch holes and 'protect the stitches,

The;y foregoing detailed description 'describes the repairing orreinforcingof one Vside only of the tire or cover but if bothes sidesare tobe repaired or reinforced-it will obvious that each side will betreated in the manner j'ust referred to andas shoiyn on the righthandside of Fig. L The said re- 4pairing orreinforcing device extend aer convenient distance op/the side ofthe coverA as shown in Fi` e. .landand may be ap-' plied or molded 'insections as sometimes .it1 is only'acertain' portion' 5ofthe cover which requires renewal as shown in iilig.Whole of the tire had to be-reinorcedy-.the endsot" the sections wouldbe joined to those or" their neighbors all around thetire'.

It is-found convenient to make theholes for the stitches with ashoemakers awl from 11o a one side of the cover and as this is being'withdrawn to followv it with a saddlers neet'he .ion

die (or' equivalent) Containing the thread. lt is necessary to adopt emethod of this character, :is if the awl is. first Withdrawn, the hole nille india-rubber closes7 so that che thread cannot pass through, but asthe :wvl is being Withdrawn the end of the needie is kept in Contacttherewith and the .two articles (awl and needle) being of metal it iseasy to 'feel Jchem in Contact as the one follows the other.

vl/hat l claim then is il. The process oi reparirinlgl or reinforcingjjlne'nnmtic tires which consists in applying ilo the interior of thetire a strip of leather molded to lit the tire, then applying on theinner and outer surfaces and around f he bend, a reinforcement ofdurable, nonstretchnble, maerial and Securing the sanne ie lie tire bytwo lines of stitchingA` one al'- the outer edge of the reinforcingstrip and the other adjacent die bead.
